Free AI Image Prompt Generator: Create Prompts for Midjourney and DALL-E

The difference between a mediocre AI-generated image and a stunning one often comes down to the prompt. A single word can change the style, mood, lighting, and composition of the generated image. But crafting the perfect prompt requires understanding each AI model's unique language.

The AI Image Prompt Generator by Jayax.dev creates optimized prompts for Midjourney, DALL-E, Stable Diffusion, and other AI image generators — turning your simple idea into a detailed, model-specific prompt.

Supported AI Image Generators

Features

1. Model-Specific Optimization

Each AI image generator interprets prompts differently. The tool automatically formats your prompt for the selected platform:

Midjourney Example:

a luxury villa in Bali, infinity pool overlooking rice terraces, golden hour, 
tropical garden, minimalist architecture, aerial drone shot, photorealistic, 
8k, ultra detailed, --ar 16:9 --v 6 --style raw

DALL-E Example:

A photorealistic aerial view of a luxury minimalist villa in Bali with an 
infinity pool overlooking lush green rice terraces during golden hour. 
The villa features natural stone walls, bamboo accents, and a tropical 
garden with frangipani trees. Warm golden light bathes the entire scene.

2. Style Presets

Choose from curated style presets:

• Photorealistic — camera settings, lighting, resolution
• Digital Art — artstation, trending, detailed
• Watercolor — soft edges, muted colors, paper texture
• Oil Painting — brushstrokes, rich colors, canvas texture
• Anime/Manga — anime style, cel shading, vibrant
• 3D Render — octane render, unreal engine, volumetric
• Pixel Art — retro, 16-bit, sprite
• Cinematic — film grain, anamorphic, dramatic lighting
• Minimalist — clean lines, negative space, simple
• Surreal — dreamlike, impossible, abstract

3. Advanced Parameters

The tool helps you configure advanced settings:

Midjourney Parameters:

• --ar — aspect ratio (16:9, 9:16, 1:1, etc.)
• --v — version (5, 5.1, 5.2, 6)
• --style — raw, expressive, cute, scenic
• --q — quality (0.25, 0.5, 1, 2)
• --s — stylize value (0-1000)
• --chaos — variation (0-100)
• --no — negative prompts

Stable Diffusion Parameters:

• Positive and negative prompts
• Sampling steps and method
• CFG scale guidance
• Seed numbers

4. Prompt Enhancement

Take a basic prompt and enhance it with:

• Lighting details — golden hour, studio lighting, volumetric
• Composition — rule of thirds, close-up, wide angle
• Color grading — warm tones, cool tones, moody
• Texture and detail — ultra-detailed, 8k, sharp focus
• Mood and atmosphere — ethereal, dramatic, peaceful
• Technical quality — photorealistic, professional, masterpiece

How to Use the AI Image Prompt Generator

Step-by-Step

1. Go to jayax.dev/tools/image-prompt-generator
2. Describe your image idea — be as simple or detailed as you want
3. Select target platform — Midjourney, DALL-E, Stable Diffusion, etc.
4. Choose style preset — or describe your desired style
5. Set parameters — aspect ratio, quality, etc.
6. Click "Generate Prompt"
7. Copy the prompt — paste into your AI image generator
8. Generate variations — tweak and regenerate for different results

Example Transformations

Simple Input:

"a cat sitting on a window"

Enhanced Midjourney Prompt:

a fluffy orange tabby cat sitting on a rustic wooden windowsill, looking 
outside with curious eyes, soft morning light streaming through lace curtains, 
dust particles in the air, cozy indoor setting with potted plants on the side, 
warm color palette, shallow depth of field, bokeh background, photorealistic, 
8k resolution, shot on Canon EOS R5 with 85mm f/1.4 lens --ar 4:5 --v 6 --style raw

Simple Input:

"futuristic city"

Enhanced DALL-E Prompt:

A breathtaking panoramic view of a futuristic megacity at dusk. Towering 
glass skyscrapers with holographic advertisements, flying vehicles navigating 
between buildings, elevated walkways connecting towers, lush vertical gardens 
climbing building facades. The sky is a gradient of deep purple to orange, 
with two moons visible. Neon lights in cyan and magenta reflect off wet 
streets below. Cyberpunk aesthetic with a utopian twist.

Prompt Engineering Tips

1. Be Specific About Style

❌ "a beautiful landscape"
✅ "a sweeping panoramic landscape of rolling green hills at sunset, with a winding river reflecting golden light, impressionist painting style, thick brushstrokes, vibrant colors"

2. Include Technical Details

❌ "a portrait photo"
✅ "portrait photograph of a woman, Rembrandt lighting, shallow depth of field, shot on Hasselblad, 85mm f/1.4, natural skin texture, editorial style"

3. Use Negative Prompts

Tell the AI what to avoid:

• Midjourney: --no blurry, deformed, ugly, text, watermark
• Stable Diffusion: Negative prompt: blurry, low quality, deformed, ugly, text, watermark

4. Specify Composition

• "centered composition"
• "rule of thirds"
• "bird's eye view"
• "worm's eye view"
• "close-up portrait"
• "wide establishing shot"

FAQ — AI Image Prompt Generator

Do I need an AI image generator account?

This tool generates prompts — you still need access to an AI image generator (Midjourney, DALL-E, etc.) to create the actual images.

Can I use the generated prompts commercially?

Yes. The prompts are yours to use however you wish. However, check the terms of service of the image generator you use regarding commercial use of generated images.

How do I get better results?

• Be more specific in your initial description
• Include reference styles — "in the style of Studio Ghibli" or "like a National Geographic photo"
• Add lighting and mood — these dramatically affect the output
• Iterate — generate multiple prompts and try them all

What's the difference between Midjourney and DALL-E prompts?

Midjourney prefers comma-separated keywords with technical parameters. DALL-E prefers natural language descriptions that read like sentences. The tool automatically formats for your chosen platform.

Can I generate prompts for AI video generators?

Currently, the tool focuses on static image generators. Video prompt generation (for Sora, Runway, Pika) may be added in the future.
